The consistency of self-discharge is an important part of the influencing factors. The SOC of a battery with inconsistent self-discharge will be greatly different after a period of storage, which will greatly affect its capacity and safety.The research on it is helpful to improve the overall level of our battery pack, obtain a higher life and reduce the defective rate of the product.A battery with a certain amount of charge, at a certain temperature, after being kept for a period of time, will lose a part of its capacity, which is called self-discharge.To put it simply, a self-discharge is a loss of battery capacity when the battery is not in use, such as the negative charge returning to the positive or the battery's charge being lost through a side effect.
The importance of self-discharge
At present, lithium batteries are used more and more widely in various digital devices such as laptops, digital cameras, digital video cameras, etc. In addition, they also have a broad prospect in automobiles, mobile base stations, energy storage power stations, etc.In this case, the use of the battery is less isolated and more in the form of a series or parallel battery pack.
The capacity and life of a battery pack depends not only on each individual cell, but also on the consistency of each cell.Poor consistency can be a huge drag on a battery pack's performance.
